Abstract
A strategy was developed to reversibly switch on/off an autonomous DNA nanomotor that contains a DNA enzyme. The multiple RNA cleavage of the DNAzyme powered the motor to move, and a strand displacement mechanism provided the basis for a reversible brake to the motor.
摘要
一种策略被开发出来，用于可逆地开启/关闭一种包含DNA酶的自主DNA纳米马达。DNA酶的多次RNA切割为马达的移动提供动力，而链置换机制为马达的可逆制动提供了基础。
